T0 all whom zlt mag concrn:

Be it known that I, THORSTEN VON ZWEIG- BERGK, 21 subject; of tl1e King of Sweclen and Norway, residing ab Olevelancl, in 13l1e county of Cuyahoga and State of Ohio, have invented 21 certain new ancl usef 111 Improvementin C011- rollers, of whicl1 tl1e following is a full, clez1r, und exact deseription, reference being l1ad Co be, aeeon1pan3 ing drawings.

My iuvention is f01 21 controller intended partieularly for use 011 street-cars 01' 0ther places wl1ere i'm may be subjee to tl1e indemency 0f tl1e weathein It is very importani; tl1at the interior of the eontroller be kept per feclaly dry, so tl1a tl1ere will be 110 arcing 01 grounding of the currenu. Heretofore there l1as been much trouble from tl1e water leakin g in around the shafts 0f 11110 controller-eylin= ders. vent such lealmge fron1 1eaching the 0011- troller-contacts.

The invention consists 0f alle means I emp1oy fo1 abtaining this objecb, whieh means 11121y be broadly stated as consistig of 21 001- 1:11 surrounding tl1e shaft 01: the eontrollercylinder zu1d a trougl1 beneatll that 0011211 adapted 130 receive tl1e water passing olf tl1e 0011211 2111(l convey it from tl1e shaft. The specific arrangement I hzwe shown f0r this is also my invenoion.

The dmwings show tl1e best embodiment of my invention 2113 present known t0 n1e.

Figu1e 1 is afront elevation 0f 51 contmoller containing my invention, 21 portion of the f1011i1 casing 01 sheath being broken away to t0 show 11l1e interior. Fig. 2 is 21 side elevation, partly sectional, of tl1e same. Fig. 3 is a plan of tl1e controller with the top platze removed.

Refenii1g t0 the parbs by leuters, A repre sents the controller-frame, made, preferably,

0'f cast-iron and provided Witl1 means whereby il1 1n21y be secured in position in ehe usual mzu1ner.

B represents the usual shiaath covering die freut a-nd sides 0f the eonoroller.

Projee'ring forward f1om tl1e eo11mollerframe, 11e:11* its upper end, is 21 plate a. This plae is inelined 130 11l1e 1ear zmd has a, W2111 a 1ising f10n1 its freut anti ende. Au opening a is provided through tl1e fr2une 2113 bhe The objeet of 111y invention is o0 p1eback of the plate a. Tl1us m1y water faliing on this plz1te a drains 01113 0f the controller. Secured 130 the f1011t edge 0f this platze a 01, 1nore properl y, t0 a boss a carried thereby me capblocks O, whicl1, Will 11l1e boss, eonstitute 13110 bearings f01 the shafts of l1l1e eontroller-eylinders. These shafts, 0f whicl1 tWo are sl1own as illustrative 0f any convenient uumber, zue designated D and E. Theyare jourualed ab tl1eir lower ends in suitable bearings {111d earry propely-shaped eonacn-plates. As shown in the drz1wings, tl1e eontact-plalaes on ol1e sl1aft D compose the governing and those 011 the shaft E the reversing cyli1'1ders. d and e represent the ordinary handles for-these shafts. The upper side of the cap-blocks O is extended rearwarclly 11p011 eacl1 sicle 0f the sl1aft wl1ich die block embraees, and 21 U-sl1aped groove c is forn1ed in this upper surface. Tl1is g1oove projects over the front Wall a 0f tl1e plante a. Rigidly secured 150 tl1e shafbs D and E, above bl1e groove c, are suitable collars F F, whiel1 211e prefembly shrunk or forced 0nto tl1e shafts and have their upper surfaees flaring downwarcl, 21s shown. These co llars projeet over the U-shaped groove c, tl1e unter side 0f the (3011211 ab the fronb of tl1e controller being o ver the medial 1ine 0f tl1e groove and ab the rear where it is 11013 over the groove being over the Plate a.

As ehe collars E and .F a1e so tigl1t 011 tl1eir sl1afts that 110 Wittel' 02111 geb between them and the shafs, it follows 1311211: any wz1ter trick= 1ing down tl1e sides of 'ohe shafts Will l0e cm 1ied by these collars away fro1r1 the shaft and drip into the groove c 01 direetly onto tl1e plate a. The grooves carrj thdwater to tl1e plate and the plaue fron1 tl1e 0011111011121,- tl1e whole Tabus constituting a trougl1 receiving tl1e weiser dripping from the collar und. cmry ing it from r.he controller.

G represents tl1e top plate of 11l1e controller, which is above tl1e draining mechanigm deseribed. The latter thertafore is' hiclden from view and 11011 only does not interfere wioh'the proper obse'rvanee 0f the indieaor positions marked 011 tl1e upper surface 0f thetop pli1te b111: does 11011 obstruct tl1e removal 0f filmt plate The oop plate surrounds nl1e sl1afts D
